BURGLAR AND FIRE ALARM.

SPECIFICATION forming peut of Letters Patent No. 787,372, dated April18, 1905.

Application filed September 30,1904. Serial N07 226,669.

Be it known that we, ll'tLLIAM Guaas and llnNnY Hausnr, citizens of thcUnited States, residing' at Mammoth, in the county of Kauawha and Stateof lVest Virginia, have invented certain new and useful Improvements inBurglar and Fire Alarms, of which the following' is aspecilicatitm, reference being' had therein to the, accompanying' drawings.

()ur invention relates to door and window stops and alarms, and morelparticularly to that class wherein a stop of the character described isconnected with au electrical alarm attachment, the object of theinvention being' to provide a device of the characterdescribed thatshall be simple and inexpensive in construction. durable, and effectiveiu operation and that can be readily adjusted to any door or window insuch manner that the pressure thereof upon the stop will close thecircuit and cause an alarm to be sounded.

A further object of our invention is to provide a device of thecharacter described that can also be used as an etl'ectual alarm in caseof a lire.

ln the drawings accomjainying' this specilication and made a part hereofwe have illustrated a preferred embodiment of our invention. and whilechanges of detail will be sug'- g'ested to one skilled in the art suchchaug'es or modilications come well within the scope and spirit of ourinvention as disclosed and claimed, and we do not, therefore, desire tobe limited to the exact construction shown.

ln the drawings, Figure l is a perspective view of the corner of a room,illustrating our improved alarm in position. Fig'. Q isa horizontalsection taken through the means for cormecting' the alarm with a door.Fig'. 3 is a similar view showing' the same applied to a window. Fig'. lis a detail section showing' the upper-wire support.

Like referencc-numerals designate corresponding' parts in all thel'ig'urcs of the drawing's.

l designates a stop pivotally mounted on a projecting' lug' or cleat 2,secured to the wall adjacent to the door. This stop is provided with apin I5, having' a sharpened point '-l. The pin 3 works within a hole 5in the Stop,

being' held in place by means of a small lug' plate t5, which projectsover thc hole, leaving' a small space for the reception o f the point l.'lo cach plate is secured a wire T, which connects with a battery b, thebattery being' connected with a bell or buzzer E). \\'hen the door lt)is opened, it comes in contact with the pin 3, pushing' it forward. Thismovement brings the pointl into engagement with the plates (3 and closesthe circuit by reason of the connection of the wires T with the batteryand causes the alarm to be sounded b v the bell or buzzer. It will beobserved that by reason of the stop 1 being' pivotally mounted on thelug' 2 it can be pulled out of the way of the door during' such times asit is not needed, so that it will not interfere with the free. opening'and closing` thereof.

ll designates a stop similar to stop l. This stop is secured to thewiinlow-frame adjacent to the sash and is provided with the samecircuit-closing' arrangement as stop 1, in which 12 .lesig'nates the,pin, 13 the point, and Il the plates to which the insulated wires T aresccured, these wires being' connected with the battery S. A projecting'lug' or arm 15 is pivotally mounted on the wimlow-sash, so that whensame is not in position for (,)peration it can be pulled to one side.,permitting' free operation of the wimlow-sash. 'hen an attempt is madeto raisel the sash, this lug', beingin operative position, is broughtinto coutact with the bottom of the pin 12, pushing' the same upward,bringing' the point l?, into engagement with the plates 1l, thusclosing' the circuit and causing' the alarm to be sounded by means ofthe bell or buzzer 9.

lt designates hooks depending' from the walls of the room in which ourdevice is used. A thread or cord 1T is stretched across the hooks andacts as a support for the upper wire. lVhen a lire occurs, the thread orcord is quickly burned away, causing' the upper wire to fall into thehook lt, thus closing' the circuit and sounding' the alarm by means ofthe bell or buzzer.

lt will be readily observed that the battery IOO and bell can be placedwhere desired in a room, either above, below, or opposite a door orwindow, or they can be placed in a house or building at a distance fromthe one in which the devices shown in Figs. 2 and 3 are placed. Forillustration, the said devices illustrated in Figs. 2, 3, and 4 can beplaced in a factory, store, or shop and the battery and bell in aresidence in such position as to immediately sound an alarm in case of[ire or burglary. v

Having thus described our said invention, what we claim as new, anddesire to secure by Letters Patent of the United States, is-

1. A combined window-stop and alarm comprising a pivotally-mounted stop,a pin slidably mounted in a hole in the stop, a plate arranged on thestop on either side of the hole, av point on the pin arranged to engagewith the plates and close the circuit, a battery, a bell, a plurality ofwires connecting the bell, battery, and plates, so that when the pointon the pin engages the plates, it closes the circuit and rings the bell,substantially as described.

2. Acombined window-stop and alarm comprising a pivotally-mounted stop,a pin slidably mounted in a hole in the stop, a lug on the pin arrangedto slide within the slot in the stop and to hold the pin in place,aplate arranged on the stop on either side of the hole, and a point onthe pin arranged to engage the plates and close a circuit, substantiallyas described.

- 3. A combined window-stop and alarm comprising a pivotally-mountedstop, a pin slidably mounted in a hole in the stop, a plate arranged onthe stop on either side of the hole, and a point on the pin arranged toengage the plates and close a circuit, substantially as described.

4. An alarm comprising a pivotally-mounted stop arranged to engage witha door, a pin slidably mounted in the stop, a lug on the pin arranged toslide in a slot in the stop, and to hold the pin in place, and a platearranged on either side of the pin and adapted to be engaged thereby,whereby the circuit is closed, substantially as described.

An alarm comprising a pivotally-mounted stop arranged to engage with adoor, a pin slidably mounted in the stop, a lug on the pin arranged toslide in a slot in the stop, and to hold the pin in place, and a platearranged on either side of the pin and adapted to be engaged thereby,whereby the circuit is closed, a battery, a bell, wire connectionsbetween the battery and bell and leading to the plates so that when the4circuit is closed the bell is sounded, substantially as described.

In testimony whereof we hereunto aiiix our signatures in presence of twowitnesses.
